A Next.js application that allows you to configure API overrides to intercept and modify API responses. When a request matches an override, it returns the override data; otherwise, it proxies the request to your main API.

It supports override API for mobile app, server side request and client side request.

Key features:

• Web UI for configuring overrides and main API settings
• Proxy API endpoint that other applications can request
• Full request matching (method, path, headers, body)
• Override management - Create, read, update, and delete overrides
• Main API configuration with authentication headers and timeout settings
